backup setting up

I have two hard drives on server. One is just for backup but I don't know how to point backup to it.
When I access Format/mount in WHM here is info I get:
Found Disk: hda (Partition,Format and Mount disk)
Found Disk: hdd (Partition,Format and Mount disk)

But in server information I get this info which is not similar to the one from
Format/mount section.
hdc: diskname, ATA DISK drive
hdd: diskname, ATA DISK drive
As You can see hard disks are HDC and HDD but up there WHM said that Found disk
is HDA and HDD ?
What is it about

Let's say that empty disk is HDD and I want to point backup to this disk. How can I do this, how to access this disk. Do I have to assign drive label "backup" or I must create partition "backup". I learned that I can do this with Disk Druid or fdisk but I don't know how to access this point to start this procedures. On redhat.com I found this but they are talking about procedure if it is on PC installed but I'am accessing server from remote location. it is Linux RedHat 7.3

Thanks
